how to combine two rrd files?<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV>Hi all,</DIV>
<DIV> </DIV>
<DIV>I am using Drraw 2.1.3 to create graphs from data that is collected for
Orca use on Solaris systems. Orca is good at it's own graphs but
sometimes its nice to get on the fly output as well. Usually I can get simple
graphs but I am at the point now where I need to do some math on the RRDs.
</DIV>
<DIV> </DIV>
<DIV>I have not been succesful in combining output from RRD files to give me a
SUM, i.e. one RRD is cpu_usr, the other is cpu_system. To get the total
utilization I need to add these two together but I can't figure out how to do
it. Everything I have tried in the CDEF sections has failed, probably
because I am at a loss as to what needs to go where. </DIV>
<DIV> </DIV>
<DIV>Can anyone help me?</DIV>
<DIV> </DIV>
<DIV>Thanks.<BR clear=all></DIV></BLOCKQUOTE></BODY></HTML>
